All this had to be done very quietly. One or two would work at it while others attracted the attention of the Germans by creating some excitement in distant corners of the camp.
The night before the camp was to be inspected, the break was made. The sixteen men were divided into four groups of four each, one in each group acting as a leader.
The first group, with Lieutenant Isaacs leading, was to get over the two fences from the windows by crossing on the bridges. The second group, led by Lieutenant Willis, was to cut its way through the wire fences. The third had ready some ladders made of strong rope, by which they hoped to climb over the fences. The last group intended to rush out with the guards when they ran through the gates to catch those who were jumping from the bridges.
At 10:30 that night, a signal was given and everything followed like clockwork. One of the prisoners short-circuited the wires, shutting off the electric lighting system and the current in the wire fences. There was no moon, and the camp was left in utter darkness.
At first the guards did not suspect anything, thinking the affair just an accident.
But immediately Isaacs began cutting away the bars at the window. When this was done, the prisoners helped him and his companions to throw over their bridges. The first man got out upon this flimsy bridge and when he was half way over, the inner end of the board was pushed out farther and farther until it touched the outer fence. Reaching the end, the man sprang to the ground, the inner part of the bridge was drawn back in by the prisoners at the window, and another man crawled out. This was continued until the four men had gone. It had been decided that the lightest man in the company would try getting over the bridge first, and Lieutenant Isaacs being the lightest led his group across.
When he dropped to the ground, he landed on his hands and knees not six feet from two German sentries, both of whom fired but did not even touch him. Without waiting for the others he ran into the woods to a spot two miles from camp which he and Lieutenant Willis had chosen for a meeting place, if they should get away safely.
Unprepared, as always if taken by surprise, the Germans when they realized the meaning of the disturbance rushed wildly about, one officer shooting frantically straight up into the air.
